VALVE FOR WATERHCLOSETS, deo.

SPECIFICATION forming part of Letters Patent No. 398,149, dated February 19, 1889. Application tiled November 12,1888. Serial No. 290,524, (No model.)

To all whom t may concern:

Be it known that I, EDWARD HAMMANN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Valves for lVater-Closet Cisterns and the following is decla-red to be a full and exact description of the same.

Valves for water-closet cisterns have been provided with a regulating device that allowed the valve to close gradually after it had been lifted.

My invention relates to a tubular standpipe having openings through its base and supported within the thimble that connects the flushing-pipe to the' cistern and forms at its upper end the valve-seat, and there is a tubular pendent guide to the valve surrounding the stand-pipe, so that water is drawn into the pendent guidepipe as the valve is raised, and this prevents the valve descending rapidly and regulates the flushing action.

In the drawings, Figure l is a vertical section of the cistern overiiow and float and of my improved valve, which is shown as closed. Fig. l is a vertical section of the valve as raised.

A repncsents the cisi'ermwhich is oi' anydesired size and provided with a float and sup ply valve, as usual.

B is the upper part of the discharge-pipe passing to the water-closet.

C is the valve-seat, and D the valve.

F is a rod connected to the valve D, and G the lever to which the rod F connected, and which lever is acted upon by a pull-chain and handle (near the closet) to raise and open the valve D in iiushing the closet.

The tubular thimble c pass through the bottom ot' the cistern A, and secured b v a nut, d', and is made water-tight by packingrings or cement.

The valve-seat C, upon which the val ve D rests, is at the upper end of the tubular thiin ble o, aud the lower end of the thimble is connected to the pipe B by a coupling-ring, o.

Th c stand-pipe B is of sm aller di ametcr than the interior ot' the tubular thimble a, and is received within said thimble, its upper end being closed and its lower end open, and there is a perforated ring-base, h', having a il anged edge, 5, by which it is held between an inward flange, 6, near the lower end of the thimble a and the washer 7 at the upper end of the pipe B, and said ring-base b is thereby kept in position; but it may move laterally or yield slightly to accommodate the other parts.

The lower end of the tubular overiiow E is connected by elbows to one side of the tubular thimble d, and I provide a iioat, L, in the form of an inverted bell, and having a central tube, l, surrouiniing` and sliding` upon the upper end of the overflow-tube E. Said tube Z is made with a cap, N, and a valve, o, of leather or rubber, and there are openings at e around the upper portion of the tube l, and I provide a rod, f, secured in the bridge g and passing through the cap N, and having a head,f", and the cap slides on this rod fas the float rises, the head f preventing` further upward movement. A float and overiiow like this is described and shown in Patent No. 386,9l8, in which the tube E forms the valve-stem.

The Operation of my improved valve is as follows: The lever G is tilted by the dowm ward movement of the pull-chain, and the rod F, valve D, and tube d are raised into the po sition shown in Fig. 2. The water in the cistern now rushes down the chamber a through the openings in the base li and down the pipe B to the closet. As the valve D and pipe d are raised, a partial vacuum is created between them and the stand-pipe b, which, as the water flows into the thimble a, causes the water to rise and iill the space between the i, pipes d and b. The lever G is now released and assumes its normal position, and as it no longer holds up the valve D said valve is free to descend to its seat, which it will do gradually, because the water between the pipes d and b holds up the valve; but the water is forced out gradually by the weight of the valve, the pipe acting as a `guide for the pipe d, and causing the valve I) to come properly to its seat. The valve may be raised to a greater Or less height, and thereby the time of closing will be varied according to the quantity of water that has to pass out from between the stand-pipe h an d the tubular hanging guide of the valve.

I claim as my invention- IOO 1. The Combination, with the eistern and discharge-pipe to the Closet, of a tubular thinble passing through the bottom of the cistern and having a valve-seat at its upper edge and eonneeted to the discharge-pipe at its lower end by a ooupling-ring, a stand-pipe and perforated ring-base Within and secured to the thimble, a valve, and an open-ended pendent pipe from said valve, said pipe surrounding the stand-pipe, substantially as and for the purposes set forth.

2. The combination, with the oistern-valve and discharge-pipe, of the thilnhle attachedto the discharge-pipe and to the eistern and having' the Vabre-seat at the upper end and an inward flange, G, at the lower end, and the tubular stand-pipe closed at its upper end and havin g holes through its base, and a flange, 5, to pass below the flange 6, and the hanging` pipe attached at its upper end to the Valve and surroundin g the stand-pipe, substantially as set forth.

Signed by me this 21st day of September,

EDVARD IIAMMANN.
